soap

what type of reaction is occurring

a reflux reaction / saponification

what happens to any solution that evaporates

condenses in the liebig condenser and returns to the reaction vessel

why are anti bumping chips added

to ensure a smooth reaction

how is the ethanol solvent removed

distillation

where is the soap produced left

in the reaction vessel

what is done with the products in the reaction vessel

they are added to a brine solution

what happens to the soap once added to the brine sollution

its precipitated

what happens to the excess naoh

dissolved in the brine solution

how is soap isolated

by filtering the brine solution

how is the product tested

by adding soap to distilled water and a lather will form

why was the reaction mixture refluxed

to speed up the reaction

suggest a suitable heating method for refluxing the mixture and then distilling off ethanol

water bath heated by hot plateb

justify your suggested heating methond

gentle heating

why is it desirable to remove all ethanol

it improves yield

what is the co product of this reaction

glycerol

what is brine

saturated solution of salt

what is the function of brine in this procedure

to precipitate soap

how was the soap seperated

filtering

where is the excess naoh when soap is being filtered

in the brine

why is one end a soap molecule is water loving

its polar

why is it important to thoroughly wash the soap in stage 4

to remove naoh

how should the soap have been washed

in brine
